`vides series of .air part-ments O, O, between the side walls and' lments may be had'through hand-holes arsecured angle bars j, j, to which are connected plates J, J, which form the. lnner walls of thereof which projects above the superstructure. The inner Walls are arranged in vertical alinement with the walls H. Adjacent to the angle bars j, are similar bars j', j', also l purpose presently stated. The wallsmJ, and J', are braced and held apart by angle bars, or I beams K, K, which vide air tight joints. The vStringer plate is provided with an elongated opening that extends practically the full length of the turret. 2 M, M, designate castings which form the, front 'and rear ends of the turret and each is constructed withvertical flanges m and m' to which the inner and outer Walls J and J' respectively of the turret are connected. At their upper and lower edgesthe castings are constructed with lhorizontal' anges m2 and ma, res ectively, the latter resting upon and dpto the Stringer plate. Each casting is formed with a semi-circular socketmt, in each of which is held a rapid regun N, the latter having spherical shaped enlargements on their barrels which snu ly it the sockets and are held` thereinby. glands These glands also prevent ingress of Iwater to the turret at-these points when the vessel is submerged; Immediately above the gun sockets the castings are provided with smaller sockets m, in which are centered sighting in` struments N', which are connected to and Gland rings To'the up er edges of the walls J are secured angle ars Z, Z, w ich extend nearly the entire length of the Walls and have their ends abuttin ladgainst the flanges of the end castings M, and tov these bars is secured a turret. Upon the p te are securely fastened angle bars or I beams K K', Fig. 2 whose practically a conbars or beams K, rests a plate tinuation of the vertical the outer edges of theplate being'secured to ofthe turret -by angle plates Z', Z', which are secured to the said outer walls adjacent' vto the upper edges thereof, and all of' the joints are sealed airand water-tight. This arrangement pro-l and water tight comwithin the top at'the forward and rear ends of. the turret. Access to the said compartyoliienings 02, 02, each cf which is coin ranged in and adjacent to the lower ends of the walls'J, which are normally closed by plates 0, 0.

o', `0',designate strengthening bolts which connect the walls J, and J', immediately above the hand-holes. The compartments O, may be utilized as ballast or storage tanks or for the reception of a suitable filling such as cellulose, pitch or the like, which will ous purposes, but also provide a construction e of very light weight kand that is strong and durable, and it will be readily seen that should any one of the compartments be penetrated, the others will remain intact and therefore the danger of the whole turret being incapacitated or flooded is greatly reduced. I

One of the compartments0', near the center of the turret, is utilized as an air duct for conducting fresh air to the interior of the vessel'when the latter is running upon, or immediately adjacent to the surface With only the turret labove the. water, and this compartment communicates with an air inlet hood P, through an opening p', formed in the top plate of Athe turret, and which is controlled by a valve p', the stem'of which extends through a casting p2, held over an openingformed in the inner plate of the top of the turret and has a hand wheel upon the extreme lower end by which the position' of the valve is controlled. A cross beam K2, Fig. 5, extending across the top of the turret adjacent to the valve p2, is bowed outwardly and extended around the valve opening s0 as to make an uninterrupted passage or duct from the opening p, to each side of the vessel. The lower end of the hood P, surrounds thc opening p 'and its upper end is formed with a rearward extension P', which terminates in a down-turned air inlet section that is controlled by a valvePg, mounted upon a stein P3, whose lower end extends through a stuffing box P", into the interior of the turret and carries an operating hand wheel at its extreme lower end. P5, designates a perforated protecting hood which surrounds the down-turned end of the hood P and the valve P2. j

Adjacent to the lower end of the ducts O', the walls J, of the 'turret are formed with -red by a U-shaped casting O2, secured to the `Walls and which extend downwardly along the l Ph .

Access to the turret may be had through a manhole S, Fig. 2 in the top of the turret which is closed by a cover S, and also through a man-hole S2, arranged in the hull of the vessel, preferably in alinement with the man-hole S. The manhole S2, is closed by a cover S3.

T, T, Figs. 2 and 4, designate dead lights arranged upon each side of the turret at intervals throughoutitslength and T, Fig. 6, a dead light arranged in the top of the conning tower.

U designates asighting instrument projeeting through the top of the turret and a casting U', held between the top plates and which may be used when the vessel is running completely submerged.

The ends of the turret are protected by wooden buffers V which are securely bolted in position and serve to protect the turret should it encounter an obstruction when running submerged. In front of the buffer atthe lower forward end of the turret is a beam V, having a recess into which the end of the gun at the forward end of the turretmay rest when not in use. The top of the turret is covered by a wood decking V2, which is held in place in any suitable manner, the outer edges of which rest upon cleats secured to and adjacent-to the upper ends of the side walls J of the turret.

From the foregoing it will be seen I provide a vessel well adapted for surface and submarine operations and possessing defensive features which may be employed in warding ofattaeks from.. light craft when pursuing the mission assigned to it without resorting tothe use of the torpedoes as defensive weapons.
